Mr T never needed the Senate's permission for nothin'. If he wanted a land bill carried, he would use his brute force and intimidating gold chains - shining, radiant, like the sun - or would reunite the entire A-Team and get the A-Chief and munitions expert Hannibal to rig up some kind of mini-Nuke explosive that would make MacGyver blush and wet his incontinence pads with envy. The only others who evem came close to his 'T-tastic' shows of strength were the Gracchi, Tiberius and Gaius. These two daring reformist brothers attempted and often succeeded in gaining greater political 'stuff' and upheaving land distribution by unconvential means - mainly by repeatedly bypassing the Senate and taking proposed legislation to the People's Assembly, much like today's Lesbian Midgets Who Have Decided To Elope With A Racist Harley-Davidson Motorcycle And Become Kindergarten Teachers take their case straight to The Jerry Springer Show for a sympathetic (emphasis on 'pathetic') forum.
Their motives in taking these measures were in some ways similar, although Gaius' motivation in trying to carry his brother's land bill and take revenge against Tiberius' opposition were more reminiscient of one of those Chuck Norris movies where his whole family is killed by Separatist revolutionaries and he goes out, wearing only a bandanna, to avenge them. Tiberius gained impetus to strive hard for reform, possibly at the risk of losing his political career, after seeing the plight of the slaves in Etruria. Gaius was motivated to motivated to continue Tiberius' legacy and avenge his death, and to also achieve some form of aid of a managed share portfolio. This quest explains why, in 133B.C., Gaius "Walker, Texas Ranger" Gracchus was seen winging his way to riches on Who Wants To Be A Millionaire. Indeed, it was Gaius' staunch refusal to use ANY of the 'lifelines' and instead to use his own wits and walk away with thousands of talents in booty which earned him such a reputation for his apititude and bravery. Eddie McGuire is quoted in Plutarch: Life of Eddie as saying "I was amazed...that Gaius sure knows his Greek history!...I've never seen such a display of valour, even in all my years as host of the AFL Footy Show..." [Plu. Life of Eddie V, iii] Tiberius Gracchus, it has been claimed by some sources both both Ancient and Modern, was motivated more by a want to feed his own interests - yet this can be disputed when, as Sculalrd says, after his visit to Etruria: "[It] urge[d] a generous-hearted man to risk his own politcal future in an attempt to re-establish the peasants on small-holdings once again".
As it can be seen, sources vary on what drove Tiberius, but it is obvious that, whatever it was, he was extremely determined to meet his objectives as - on several occassions throughout his tribunate - he undermined the Senate's authority and generally behaved like a real dick.
Well, sources are varied on this whole 'dick' thing, too.
